我的 $_Post 不起作用。当我用var_dump打印它时，它说数组中有 0 个项目。这是代码
<form method = "post" action = "contact-process.php">
<table>
<tr>
<th>
<label for = "name">Name</label>
</th>
<td>
<input type = "text" name = "name" id = "name">
</td>
</tr>
<tr>
<th>
<label for = "email">Email</label>
</th>
<td>
<input type = "text" name = "email" id = "email">
</td>
</tr>
<tr>
<th>
<label for = "message" >Message</label>
</th>
<td>
<textarea name = "message" id = "message" ></textarea>
</td>
</tr>
</table>
<input type = "submit" value = "Send">
</form>
<?php
var_dump($_POST);
$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];
echo $name;
echo $email;
echo $message; ?>
这是我的表单和联系流程的 html 代码.php代码var_dump 命令返回 0 个项目，回显变量返回未定义的索引："名称"、"电子邮件"、"消息"
var_dump返回 0，因为它在第一次加载时没有任何元素。因此，设置一个条件来检查是否单击提交按钮的天气。
您需要指定 的名称属性以进行检查。
<form method = "post" action = "contact-process.php">
<table>
<tr>
<th>
<label for = "name">Name</label>
</th>
<td>
<input type = "text" name = "name" id = "name">
</td>
</tr>
<tr>
<th>
<label for = "email">Email</label>
</th>
<td>
<input type = "text" name = "email" id = "email">
</td>
</tr>
<tr>
<th>
<label for = "message" >Message</label>
</th>
<td>
<textarea name = "message" id = "message" ></textarea>
</td>
</tr>
</table>
<input type = "submit" value = "Send" name="submit">
</form>
<?php
if(isset($_POST["submit"]))
{
var_dump($_POST);
$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];
echo $name;
echo $email;
echo $message;
}
?>
我希望这能完成你的工作。 :)
